‘Noise-cancelling’ qubits developed at UChicago to minimize errors in quantum computers
Researchers at the University of Chicago have developed a new method to constantly monitor the noise around a quantum system and adjust the qubits, in real time, to minimize error. The approach, described in "Science," relies on spectator qubits: a set of qubits embedded in the computer with the sole purpose of measuring outside noise rather than storing data. The information gathered by such spectator qubits can then be used to cancel out noise in vital data-processing qubits. Read More

UChicago scientists invent ‘quantum flute’ that can make particles of light move together
From University of Chicago: Q-NEXT collaborator David Schuster and team have invented “quantum flute” that can coerce particles of light to move together in a way that’s never been seen before. The breakthrough, reported in Physical Review Letters and Nature Physics, could point the way toward realizing quantum memories or new forms of error correction in quantum computers and observing quantum phenomena that cannot be seen in nature.
